Need to figure out which variant I want to make or does it HAVE to be a hellhound, as written?
Upon checking out the Hellhound Squadron entry,
1 Hellhound, 1 Devil Dog or 1 Bane Wolf
So you're good to go on any of the variants.
between these two the standard hellhound seems a bit. sad.
It's true, though if you're not facing 3+ saves the fact that the Hellhound has a Torrent weapon really helps it out over the chem cannon's short range. Against a RW bike squad with few numbers you're winning, but against a unit with multiple wounds per model (or just more models in the unit) I find its range leaves it too open to a counter attack.
